Mass transfer device and mass transfer method

1. A mass transfer device, wherein the mass transfer device is provided with multiple channels of which two ends are opened, each channel comprises a first opening and a second opening, the first opening of each channel is arranged on a first surface of the mass transfer device, the second opening of each channel is arranged on a second surface opposite to the first surface, and distances between the channels are gradually increased along a direction from the first surface to the second surface.

2. The mass transfer device as claimed in claim 1, wherein the channels are straight lines.

5. The mass transfer method as claimed in claim 4, wherein the connection material is a welding flux.

6. The mass transfer method as claimed in claim 3, wherein a material of a portion, connected with the first substrate, of the Micro-LED is GaN.

7. The mass transfer method as claimed in claim 6, wherein the first substrate is a growing substrate of the Micro-LEDs.

8. The mass transfer method as claimed in claim 3, wherein the Micro-LEDs are connected with the first substrate by photolytic glue.

10. The mass transfer method as claimed in claim 9, when the Micro-LED is in a state of connecting with the first substrate, an existing electrode of the Micro-LED faces to one side away from the first substrate.

13. The mass transfer method as claimed in claim 12, wherein the through holes are installed corresponding to the Micro-LED to-be-installed positions on the second substrate.

15. The mass transfer method as claimed in claim 14, wherein a material of the mass transfer device is an anti-static material.
